我正在尝试创建一个单页应用,从JSON文件中提取信息,将其显示在屏幕上,然后执行一些操作。
现在,我已正确显示所有信息:http://jsfiddle.net/rcsayf7t/3/
我需要“删除”按钮,以便在点击时从屏幕上异步删除JSON对象,但遗憾的是我不知道如何完成它。
HTML:
<table>
<thead>
<tr>
<th scope="col"></th>
<th scope="col">Name</th>
<th scope="col">Message</th>
<th scope="col">Date</th>
<th scope="col"></th>
</tr>
</thead>
<tbody class="tweets-result"></tbody>
</table>
jQuery的:
// helper function for formatting date
function formatDate(date) {
var dateSplit = date.split(" ");
var displayDate = dateSplit[0] + ", " + dateSplit[1] + " " + dateSplit[2];
// return the result
return displayDate;
}
$(document).ready(function () {
// start ajax request
$.ajax({
url: "https://gist.githubusercontent.com/arlodesign/7d80edb6e801e92c977a/raw/24605c9e5de897f7877b9ab72af13e5b5a2e25eb/tweets.json",
dataType: "text",
success: function (data) {
// store the JSON data
var tweetData = $.parseJSON(data);
// loop through json values and build the table
$.each(tweetData.tweets, function (index, item) {
$('.tweets-result').append(
'<tr>' +
'<td><img src="' + item.profile_image_url + '" alt="@' + item.screen_name + ' avatar"></td>' +
'<td><a href="https://twitter.com/' + item.screen_name + '">@' + item.screen_name + '</a></td>' +
'<td>' + item.text + '</td>' +
'<td>' + formatDate(item.created_at) + '</td>' +
'<td>Remove</td>' +
'</tr>');
// WHEN YOU CLICK "REMOVE", THE TWEET SHOULD
// ASYNCHRONOUSLY BE REMOVED FROM THE SCREEN
});
}
});
});
答案 0 :(得分:1)
只需在ajax成功中添加以下内容:
$('.remove_row').click(function(){
$(this).closest('tr').remove();
});
以及以下代码作为删除属性:
class="remove_row"
Full JS(阅读我的评论):
// helper function for formatting date
function formatDate(date) {
var dateSplit = date.split(" ");
var displayDate = dateSplit[0] + ", " + dateSplit[1] + " " + dateSplit[2];
// return the result
return displayDate;
}
$(document).ready(function () {
// start ajax request
$.ajax({
url: "https://gist.githubusercontent.com/arlodesign/7d80edb6e801e92c977a/raw/24605c9e5de897f7877b9ab72af13e5b5a2e25eb/tweets.json",
dataType: "text",
success: function (data) {
// store the JSON data
var tweetData = $.parseJSON(data);
// loop through json values and build the table
$.each(tweetData.tweets, function (index, item) {
$('.tweets-result').append(
'<tr>' +
'<td><img src="' + item.profile_image_url + '" alt="@' + item.screen_name + ' avatar"></td>' +
'<td><a href="https://twitter.com/' + item.screen_name + '">@' + item.screen_name + '</a></td>' +
'<td>' + item.text + '</td>' +
'<td>' + formatDate(item.created_at) + '</td>' +
'<td class="remove_row">Remove</td>' + // ## Here add the class remove_row
'</tr>');
// WHEN YOU CLICK "REMOVE", THE TWEET SHOULD
// ASYNCHRONOUSLY BE REMOVED FROM THE SCREEN
});
//## Here assign the even on click for the remove button
$('.remove_row').click(function(){
$(this).closest('tr').remove();
});
}
});
});
